PlSql Procedure Parameter

Hi
i would like to know if using varchar parameter in sql queries with number column can result in performance degrade.
Ex: Procedure testa ( myparam varchar) is
begin
select col1 into var1 from table where colno = myparam;
end;
Here colno is a number column and myparam is varchar. I feel its better to change the parameter to number. But i would like to get some advise before considering to change such occurences across my backend codes.

In all versions of Oracle, including the version you are using and which you didn't bother to mention, implicit type conversion is always on the left hand side of the comparison.
Your statement will be transformed into
select col1
into var1
from table
where to_char(colno)= myparam;
If colno is indexed, the index will NOT be used, and Oracle will use a Full Table Scan.
The best, most robust solution is to use
myparam table.colno%type
Doing so, you can alter the column without having to change the procedure.

Calling PLSQL Procedure with CLOB input parameter from JDBC

Hi..
I've got a PLSQL procedure with a CLOB object as input parameter:
function saveProject (xmldoc CLOB) RETURN varchar IS
I want to call that procedure from my JDBC Application as...
String data = "..."
CallableStatement proc = conn.prepareCall
("begin ? := saveProject (?); end;");
neither
proc.setCharacterStream(2, new StringReader(data, data.length());
nor
proc.setString(2, data);
will work.
The Application throws java.sql.Exception: ... PLS-00306 wrong
number or types of arguments in call 'SAVEPROJECT'
How can I use set setClob method?
The Problem is: with Oracles CLOB implementation I can't create
an Instance, and from the CallableStatement a can't get a
Locator for a CLOB-Object.
This CLOB stuff makes me really nuts!
please somebody help me.. thanks
Alex

Hi All,
You can not make it like that.
You can not make clob as input parameter.
Do you want an easy way?
This is the easy way.
sample:
function myFunction(S varchar2(40))
return integer as
begin
insert into TableAAA values(S)
--TableAAA only contains 1 column of clob type
end;
This will work the problem with this is the parameter is in
varchar2 right? so there will be limited length for it.
You can do this to call that function:
nyFunction('My String that will be input into clob field');
There's another slight difficult way, I understand that you have
installed Oracle client/server in your system, try to look at
jdbc folder and try to find demo.zip in that folder, you can
find several ways of doing thing with jdbc.
Have a nice day,

How to pass int array as an IN parameter to PLSQL Procedure

Hi,
How to pass int array in java to a stored procedure througn jdbc
and what type of data type I should declare to this IN parameter
in PLSQL Procedure.
Thanks,
Simi

Hi,
The best way to do what you want depends on what you want. Start by describing what you need to do. It's best to post some sample data (CREATE TABLE and INSERT statments) and what results you want from that sample data. (See the forum FAQ: https://forums.oracle.com/message/9362002)
If you have ideas about how to do the job (e.g., populating a temporary table) it can be helpful to include those, too, but distinguish clearly between WHAT you need to do and HOW you might do it.
As Bencol suggested, a SYS_REFCURSOR might be the best way to pass back the results.
Since you didn't post your table, or even describe what you wanted to do with it, I'll illustrate using scott.emp, which is probably on your system.
Say you wanted a procedure that took a DATE as an argument, and returned a some designated columns (empno, ename and hiredate in the example below) for all employees hired on or after the given DATE. You might write a procedure like this:
CREATE OR REPLACE PROCEDURE hired_since
(   start_date IN   DATE
,   out_data    OUT SYS_REFCURSOR
AS
BEGIN
    OPEN out_data FOR
        SELECT empno, ename, hiredate
        FROM    scott.emp
        WHERE   hiredate >= start_date;
END hired_since;
SHOW ERRORS
You can test it in SQL*Plus like this:
VARIABLE   c REFCURSOR
EXEC hired_since (DATE '1982-01-01', :c);
PRINT :c
The output I got from this test was:
     EMPNO ENAME      HIREDATE
      7788 SCOTT      19-APR-87
      7876 ADAMS      23-MAY-87

Doubt: Do I need to declare ArrayDescriptors to retrieve the VArray from the Plsql procedure.
I think the below statement is enough; we need ArrayDescriptors only when we we wish to send a Plsql Object or Varray from Java code to the procedure. Plz correct me if not so.
dbCallableStatement.execute();
ARRAY SimpleOUTArray = (ARRAY) ((OracleCallableStatement) dbCallableStatement).
getObject(Integer.parseInt(arlParameterOutIndex.get(i).toString()));{color}
I am unable to realize where the mistake is?

Using PLSQL procedure with parameter in AQ

hi,
we need to run a PLSQL procedure(asynchronously) with in parameters using oracle AQ.
can someone give me simple example/hint?
Many thanks

Since you mention dbms_job, can you use dbms_scheduler since you can pass in parms? You can schedule the job to run "now" and while it may have a slight delay starting up due to available processes for the scheduler and system load, it will run as soon as it can.
What are you trying to accomplish in your environment? I'm not following why you want to allow a user to schedule any DB procedure. A certain set yes, all, no.
You could create a generic AQ structure where it is passed some information regarding what procedure needs to run and what/where the parms are. This driver procedure would then be responsible for calling a random procedure via dynamic SQL. I've never tried passing parms to a procedure via dynamic SQL but recall reading you could do it. I wouldn't recommend this approach unless you have no better options though.

Employee NULL =Note this substitutes the word NULL if no empno is passed, and it ignores error output or anything else by only looking for lines beginning '# ' and then taking the following word. Error messages will appear in the logfile. (In this example it probably doesn't need the NULL substitution because a missing parameter would cause a syntax error which the script will handle anyway, but it could be useful in more complex examples.)
For a production script you should probably use an OS authenticated account so you don't have to deal with password strings.

Problem with database adapter on plsql procedure with in/out parameters

running BPEL 10.1.3.1 and using the database adapter on a plsql procedure with in/out parameters I get errors
the plsql procedure:

In BPEL I call this procedure. When I only assign a value to the p_string parameters (in a BPEL assign) all is well. When I also assign a value to the p_clob parameter the error occurs:

In BPEL 10.1.2.0 this isn't a problem. I tested it against a 10.2.0.1 and a 10.2.0.2 database and in both situations I get the error with BPEL 10.1.3.1 and no error with BPEL 10.1.2.0
it appears to be a problem in the database adapter...
anyone with the same problems and/or a solution?

Not of any use to you, but we had exactly the same problem on Friday when we applied AS 10.1.2.2 Patchset on top of BPEL 10.1.2.0.2.
The clob in our pl/sql proc wan't declared as in/out but for some reasons JDeveloper had created a clob on the Output Parameter type in the db partner link xsd. I removed this and it worked. This code had been untouched , and working fine, for months.
I'll be raising an SR today.

Help with truncating a table using plsql procedure in different schema

I have a plsql procedure in schema A that truncates a table that is given in as parameter.
create or replace procedure truncate_table(schema, table_name)
EXECUTE IMMEDIATE 'TRUNCATE TABLE '||schema||'.'||table_name;
end;
The above procedure has public execute grant.
I need to truncate a table in schema B. I have a plsql procedure in schema B that calls the truncate_table procedure and passes in the schema B table name.
Since the table is in schema B, should the delete grant on the table be given to user A or user B to truncate the table in schema B?
Thanks in advance.

Procedure created in schema A
create or replace
procedure truncate_table(l_schema varchar2, table_name varchar2) authid current_user
as
begin
EXECUTE IMMEDIATE 'TRUNCATE TABLE '||l_schema||'.'||table_name;
end;from schema B
grant delete on table1 to Schema_A
from schema A
exec truncate_table('Schema_B','Table1');
Hope this helps.

Creating a PLSQL Procedure as Concurrent Program

Folks:
I am new both to PLSQL and Concurrent program creation. I am actually working on a process for deploying changes from one environment to another, so I want to create a simpel PLSQL procedure that I can then register as a concurrent program, and finally test the download/uplaod of this procedure and program from one instance to another.
I tried reading the Developer documentation on creating concurrent program, but couldn't find the information I was looking for. Here are some of my questions:
1) The PLSQL procedure that I want to run as concurrent program, can it be declared within a new custom package, or does it have to be created as a procedure.
2) In the concurrent program executable registration window, can i specify directly the name of this new procedure or do I need to create an additional wrapper PLSQL procedure that has Concurrent Program related attribute (Developer guide seemed to incline that way).
3) What should be put in the 'File' parameter on Concurrent Program Execution Window in the case of pl/sql concurrent program. There is no file, so what to put in there?
4) Any other place I can find step by step how to for making a 'PLSQL" package a concurrent program?

Hi,
1) Create PL/SQL Package with "main" procedure that has arguments ERRBUF and RETCODE plus your other required arguments.
2) xxxx_pkg.main as per 1.
3) xxxx_pkg.main (the package and procedure name)
4) Best place to look is at an existing program! Plenty of basic examples on the net. Here's a link that has basic package and screens:

PLSQL procedure

Hi,
I have a PLSQL procedure defined in a schema which I like to run first so that it would poupulate a row in a table. I defined a pre-mapping process but it does not work. Any information would be appreciated!

There is no complication to run procedure in premapping .
You can test few thing.
1. Are you able to run it from database directly.
3.If yes then run it with same parameter as provided (if there are) in mapping.
4.Check the procedure in which schema it is defined.
Cheers

Passing multidimensional array to plsql procedure

is there any way to pass a two dimensional array of different data types to plsql procedure as a parameter?
In other words, is it possible to pass a set or records or a datatable as a single parameter to plsql procedure?
Because I am using a dataset selected with odp.net in my client and I am modifying the data in different datatables contained in the dataset.At the moment, the modified datatables are saved by seperating each column as a sepearate array and passing each column array as a seperate parameter to a stored procedure. But, I would like to change it in a way to pass each datatable as a single parameter to the stored procedure.
I would appreciate any solution/suggestion/hint in regard to this problem
thanks in advance,
Prabhakar.

If your Java array is of a base type (String, int, etc.) and you are using the OCI driver, you can use OracleCallableStatement.setPlSqlTable(). (I'm doing this from memory so the method name may be slightly different.)
The method takes a Java array and converts it to a PL/SQL table before passing it to the stored procedure.

The simplest way for plsql procedure to return multiple rows

Hi,
What is the simplest way for plsql procedure to return multiple rows (records). There are many combination of ways to do it but I am looking for a solution that is appropriate for plsql beginners. Many solutions use cursors, cursor variables, collections and more that kind of things that are complex on the face of it. Is it somehow possible to achieve the same with less effort?
Sample query would be: SELECT * FROM EMPLOYEES;
I want to use returned rows in APEX to compose APEX SQL(in that context plsql) report.
It is enough to use just SELECT * FROM EMPLOYEES query in APEX but I want to use plsql procedure for that.
Thank you!

Hi,
It depends :-).
With +...that is appropriate for plsql beginners...+ in mind... it still depends!
The list of techniques (ref cursors, cursor variables, collections, arrays, using explict SQL) you have referenced in your post can be made to work. but...
+Is it somehow possible to achieve the same with less effort?+ Less effort : That needs to be defined (measured). Especially in the context of pl/sql beginners (who is a beginner?) .
What is the level of "programming experience" ?
What is the level of understanding of "Relational Result set" as processible in Oracle?
If you are looking for
Process_the_set_of rows_in APEX () kind of capabilitywhich "abstracts/hides" relation database from developers when working on relation database, it may not be the best approach (at least strategically). Because I believe it already is abstracted enough.
I find REF CUROSOR most effective for such use, when the "begginer" has basic understanding of processing SQL result set .
So in a nut shell, the techniques (that you already are familiar with) are the tools available. I am not aware of any alternative tools (in pure Oracle) that will simplify / hide basics from develpers.

Business Event not triggering the PLSQL procedure.. What to do?

We need to call a plsql procedure when the GL Approval workflow has ended with approval. I thought i could do this by customizing the relevant business event.
We are on EBS 12.1.3 with RDBMS : 11.2.0.3.0.
I saw that the business event oracle.apps.gl.Journals.journal.approve was disabled currently. I enabled it and created a subscription for it. Subscription was a PLSQL procedure. Currently, for test purpose only thing it is doing is to insert a row into a table.
Business Event Subscription settings:
System: ORDEBS.SYSTEM.COM
Triggering Event
Source Type:Local
Event Filter: oracle.apps.gl.Journals.journal.approve
Execution Condition
Phase: 100
Status: Enabled
Rule Data: Message
Action Type:Custom
On Error: Stop and Rollback
Action
PL/SQL Rule Function: XX_GL_APPROVE_BE_PKG.Get_Attributes
Priority: Normal
Documentation (Not sure what value to be given for these. I went with the below values.)
Owner: Company Name
Owner Tag: Custom Schema
Using the below query i can see that the business event is getting called when the approval happens (One row added each time approval happened). But I cant see any rows in the table where it should insert a row. What could be going wrong? How can i verify that the procedure has been called?
select * from WF_DEFERRED where corrid ='APPS:oracle.apps.gl.Journals.journal.approve'
Procedure:
CREATE OR REPLACE PACKAGE BODY APPS.XX_GL_APPROVE_BE_PKG
AS
PROCEDURE Get_Attributes
IS
BEGIN
INSERT INTO xx.xx_test_table VALUES ('From BE');
COMMIT;
END Get_Attributes;
END XX_GL_APPROVE_BE_PKG;

Thanks Alejandro. Now this is working.
Changes i made:
1. Added the WFERROR workflow as a subscription to this event. So i could see that the function i am calling from the event did not have proper signature.
2. Changed the function signature to have standard parameters like:
CREATE OR REPLACE PACKAGE BODY XX_GL_APPROVE_BE_PKG
AS
function subscription(p_subscription_guid in raw,
p_event in out nocopy wf_event_t) return varchar2 is
l_result varchar2(20);
begin
insert into xxvtv.xxvtv_test_table values ('From BE');
commit;
exception
when others then
wf_core.context('XX_GL_APPROVE_BE_PKG','function subscription', p_event.getEventName(), p_event.getEventKey());
wf_event.setErrorInfo(p_event, 'ERROR');
return 'ERROR';
end subscription;
END XX_GL_APPROVE_BE_PKG;
3. Changed the owner name and owner tag both to the custom schema name (XX)

Passing values to between Pages from a PLSQL Procedure in third Page

Hello,
I have a form divided into 3 pages. The first Page is used to select Template which is used to call a screen Page 54 and Page 55 (Wizard Based screen).
From Page 55 (third page) of my application, When I click on Finish Button (Submit Button), a PLSQL Procedure is called which inserts values in 5 to 6 tables on a schema. The Success message include Article &DOCID. successfully Added.
When I return to the first Page which is Page 24, it displays no value for DOCID.
Sample Example =
DECLARE
DOCID VARCHAR2(30);

The Success message is as follows:
Article &DOCID. Created/Updated Successfully

Shivanand,
There's no need to post that much code when you could create a very short test case that demonstrates only the problem you are having.
You're using &NAME. notation on something that isn't a page or application item. You can't reference PL/SQL variables that way (or any other way) outside the PL/SQL scope. For your situation, you could create a page item named P55_DOCID and assign it a value in the PL/SQL process (:P55_DOCID := DOCID;), then reference &P55_DOCID. in HTML areas like the success message.
